I want to loop over seventeen variables at the same time in different lists. Zip does not work since I want to loop the second over all the others.
For example: I have the variables a, b, c and resp. lists al=(0,1), bl=(0,1,2) and cl=(0,1,2,3); I want the result to be like
a b c
0 0 0
0 1 0
0 0 1
0 1 1
...
(there should be len(al)*len(bl)*len(cl) outcomes).
The option I am trying to avoid is to write 17 loops, one on top of the other.
